Tightening enforcement of the EU's NIS2 Directive is compelling automotive and logistics suppliers across Europe to accelerate investments in operational technology (OT) security. Companies now face mandatory incident-response playbooks, segmented industrial networks, and board-level accountability for cyber failures.
Background
The EU's NIS2 Directive came into force in January 2023, marking a decisive shift in how digital risk is governed across critical sectors, including transport and automotive manufacturing. NIS2 replaced the original NIS Directive and required member state transposition by October 2024. Implementation across the bloc remains uneven. Belgium, Denmark, Greece, Hungary, Italy, Malta, and Slovakia have enacted NIS2 legislation, while Germany and France are still finalizing the necessary laws. Germany's NIS2 Implementation Act entered into force on 6 December 2025, with the BSI registration portal going live in January 2026. The European Commission has launched infringement proceedings against member states that missed the implementation deadline.
Cyberattacks are escalating: in Q2 2025, global cyberattacks rose approximately 21% versus the same period the previous year, with Europe recording the highest region-level increase. Against that backdrop, 60% of OT organizations reported a security incident in 2025, according to the Dragos 2025 ICS/OT Cybersecurity Year in Review, making compliance a pressing operational concern rather than a theoretical exercise.
Details
The directive's scope is substantially broader than its predecessor. Where NIS1 covered a narrow list of operators of essential services, NIS2 introduces two tiers-essential entities and important entities-pulling in any organization operating industrial systems in a covered sector with more than 50 employees or €10 million in annual turnover. NIS2 classifies transport as an essential sector, imposing the highest security requirements and strictest sanctions. Automotive manufacturing falls under the "important entities" category. Essential entities face proactive ex-ante supervision from national authorities, while important entities are subject to ex-post supervision triggered by evidence of non-compliance.
Penalties for non-compliance are severe:
- Essential entities can be fined up to €10 million or 2% of global revenue.
- Important entities face penalties of up to €7 million or 1.4% of global revenue.
- Executives are personally liable: NIS2 places direct responsibility on senior management. If an organization fails to implement proper cybersecurity measures, executives can face fines, legal action, or temporary bans from management roles.
On the technical side, the directive is driving a rapid shift in how suppliers architect and defend plant networks. Manufacturers are expected to implement continuous risk management processes tailored to OT environments, including identifying vulnerabilities in both legacy and modern systems, maintaining a detailed inventory of devices and data flows, and deploying controls such as network segmentation and anomaly detection. Under NIS2, significant incidents must be reported to national authorities within 24 hours, with a full root-cause impact report due within 72 hours. This requires fast detection of OT anomalies, automated logging and notification workflows, and playbooks and tools to gather evidence and draft incident reports immediately after an alert.
For logistics operators, infrastructure complexity compounds the compliance burden. Operational systems in warehouses-including automated sorting equipment, robots, and autonomous guided vehicles (AGVs)-as well as vehicle telematics and IoT sensors are rarely updated and often lack basic security. A typical logistics company works with dozens of transport subcontractors, each at a different security maturity level, requiring active management of that entire chain under NIS2.
NIS2 is particularly impactful for the automotive supply chain because of its emphasis on the supply chain itself. The directive does not merely target OEMs but places direct and indirect obligations on every level of the supply ecosystem, from Tier 1s to Tier 3s and beyond. OEMs are rapidly reassessing the cybersecurity posture of their supply networks and must demonstrate due diligence and ongoing oversight of third-party cybersecurity risks. According to industry analysts, suppliers that cannot provide adequate documentation or a clear security roadmap are increasingly viewed as liabilities and risk being phased out of future procurement cycles.
ENISA has released updated resources mapping NIS2 obligations to global cybersecurity frameworks such as ISO/IEC 27001, NIST CSF, and IEC 62443, offering a clearer picture of practical implementation in OT/ICS environments. The automotive sector also contends with the parallel requirements of ISO/SAE 21434, the international standard for road vehicle cybersecurity engineering, which OEMs increasingly embed directly into supplier contracts alongside NIS2 obligations.
Outlook
Implementation remains uneven across EU member states, but organizations that adopt best practices now will be better positioned as enforcement tightens. The EU Cyber Resilience Act (CRA), which addresses products with digital components including OT systems and industrial devices, adds a further compliance layer: CRA enforcement is scheduled to begin in December 2027, meaning automotive and logistics suppliers face a compressing window to mature their security postures across both directives simultaneously.
In Germany alone, around 29,500 companies are directly affected by NIS2 and must self-assess, register, and maintain verifiable cybersecurity measures through the BSI portal. Budget pressures are expected to intensify. Organizations frequently underestimate NIS2 costs during initial planning, often discovering that implementation demands significantly more resources than originally budgeted-a reflection of the complexity of deploying cybersecurity controls across legacy systems while maintaining operational continuity.
